.MD5 file help

hello ,
Am using galaxy ace and i want to change the default app icons [like My files gallery...etc].I downloaded a copy of my firmware and i was able to extract system.rfs from the md5 file which contained the apk for the music player...etc using 7z,i changed the icons to my custom icons...now I am not able to move the system.rfs to the MD5 file using 7z...does any one know anyway of doing this
P.S Does editing the files do harm when flashing...will this be succesfull?

If you edit rfs files on pc then its corrupted
So make changes in the apk and paste it in /system/app
You can make a new rfs fine too but that needs root and and the need to know which partition is mapped to /system

so can i just place the apk directly on phone through root explorer...but i tried that with an system app [you tube] i dont use ,i changed the icon and placed the apk using root explorer...after that it vanished..i tried rebooting and installing the apk....but it wont install...

CM file system issues

I have CyanogenMod M1 and I'm using Root Explorer 2.21.1 to navigate the files system.
The /sdcard/ section does not allow me change file permissions.
When I create a directory in the root I have full permissions but when I restart the phone the newly created folder is deleted.
Any suggestions?

I can't transfer files from pc to phone (just inside the folders)

Hi! i did a root with motochopper..and after it when i wanted to transfer a file from pc to a folder of the s 4 i saw a message like this the device stop responding or is disconnected...but when i transfer a file outside the folders i can and its all ok.So i did a reset and i installed the original german firmware that there is on net but after the reset and after i installed this firmware....i cant still transfer files inside the galaxy s 4 folders..but outside them i can.So i guess, is not the root? is a characteristic of the s 4? if not how can i solve this..i have windows 7.
Edit i rooted the phone with another method found on net..now i can put a file in many folder but not in the obb folder..why?

not entirely sure why it is like that. but the easiest fix is to move the file you want to put into obb somewhere else on your phone and then use a root explorer on your device to move it into obb.

help me how to install

my rom is stock odex i used universal deodexer and deodexed my.system/app and system/framework folders in my pc . now my question.how can i install that app and framework folders to my phone ??(i tried replace with root explorer but it does not .(how can i make thats to a flashable zip?

but
my problem is not that . i can make a flashable zip . its working fine but after i flashed old .odex files doesnt delete. how can i add it to meta inf for when flashing delete app and replace new app and same for framework

You just need to put in a simple delete line into the update script
for example
Code:
delete("/system/app/Vending.apk");
will delete the Vending.apk from the folder system/app
remember if you are manually pushing files with a root browser you need root permissions and you need to set the correct file permissions - for most apps in the app folder it will be rw-r-r

thnx
thanx i learned if i want to delete folde i will use delete_recursive

Click to expand...
Click to collapse
most likely if the status bar just doesn't show but does not display a force closed message its because the SystemUI.apk is not correctly signed
as long as the file name is correct and it is correctly compiled with no errors the only thing left is the signing
You can sign an apk easily with zipsigner (playstore)
just copy the apk to any folder on your sd card
start zip signer
select your apk as the input
select the name you want to call it for the output (make it different from the input - you can change the name later)
select platform key as the key you wish to sign (this is for system apps for user apps use a test key)
sign the apk
once done the apk will be outputted as a zip file
change the name of this zip to the name of your apk and don't forget to change the .zip extension back to .apk
put in a flashable and flash in cwm with system mounted
you can check any errors with the SystemUI.apk by doing a logcat via adb as the phone is starting up
By searching the logcat for SystemUI you will be able to see any errors in it and why its not starting - eg Signature mismatch skipping loading

[Q] How to install cereberus.apk as a system file?

Hi
I have a question because I don't know how to install cereberus.apk as a system file.
I have single .apk file but in system\app I have some folders with apk files inside.
Do I need to make folder for my apk file or only copy this and change permissions (644)?
And which is the best place for this apk:
*system\app
or
*data\app?
Thanks a lot

If you are rooted you can use titanium backup to change it from a normal app to a system app.

Alternatively you can drop the apk into system/priv-app, fix its permissions and then reboot.
